I may have come a bit late to this thread, but I am a High School teacher (Social Studies) and I've actually been personally handed similar sheets from a few students before on their first day in my class usually. It doesn't happen very often, mind you, but it has happened more than once. For example, I've gotten one from someone who considered themselves genderqueer and another student who identified as gender fluid. Both of their sheets were somewhat more passive aggressive than these ones though.

There was one Senior girl who was the worst out of all the sheet-givers. Let's call her Penelope, she was in my Government class last years, and I'll say this, she's a real pill. Her first day she walks straight up to my desk and hands me a full size white sheet of paper. On this paper, it explained in detail her identity as a Muslim femme-genderqueer pansexual, her words, not mine at all.

This paper was different though, not only was it much longer, and frankly one of the most passive aggressive things I've seen in all my years, listing the things she finds objectionable, demanding that I pronounce her chosen name correctly and refer to her by the right pronouns or she would, and I quote, "Make your life hell." What also made this sheet unique is that it had a strike system, according to the sheet, every time Penelope heard or saw me do something objectionable to her in the classroom, she would get up and put a slip of Monopoly money on my desk, signifying a strike.

She stuck to her system throughout the rest of the semester. I have many stories to tell about Penelope, I of course treated her like I'd treat any other student, but she went out of her way to be rude towards me. From what I heard from her other teachers, this was a pattern. Oh, boy, the stories I could tell...
